One of the first things people usually say when they meet celebs in person is that they're so tiny—both skinnier and shorter than they'd imagined. That was definitely true when I met Sarah Jessica Parker, followed closely by "she is THE nicest person alive." Fittingly, when SJP stopped by the White House last night, she showed off both of those traits at once, performing in a talent show with elementary school kids (so nice!), where, hilariously, she seemed about the same height as most of the third-, fourth-, and fifth-graders (so teeny!!).

Watch her sing and dance to "You're Never Fully Dressed Without a Smile" below—she pops up around the 0:50 mark—because it's adorable. And because before Sex and the City, SJP used to be a big Broadway star. (Or did you forget?)
